The concept being tested is how fluid leaves the blood stream to nourish tissues and then enter the lymphatic system. When plasma filters out of capillaries, it forms tissue fluid that bathes the cells, supplying nutrients and taking up wastes. As this tissue fluid enters lymphatic capillaries, it becomes lymph. So the term that describes this process of forming lymph from plasma as it leaves the capillaries is lymph formation. Lymphatic drainage would describe moving already formed lymph away from tissues, Cisterna chyli is a lymphatic structure, and Nutrient transport refers to moving nutrients within the blood, not the formation of lymph.
